gtkmm Treeview is slow. Any tips?

[eric jrdn <eric_jrdn2 yahoo fr>]

Hello all,
I would like to build a specific tabler/data display
with Gtkmm.

Data displaying is done with a drawing area and there
is no problem with this. When I do not need to view
the content of the data (ie just draw them) i use a
stl vector<double>  which is fast and easy to use,
even if the number of data equals something like
100000 or 1 million. But I need to delete datas with a
right click on a spreadsheet, which requires a
Treeview and a ListStore : it is too slow for this
task. Does it exist any replacement of them, more
compatible with the stl vector class? Faster?

The drawing area is linked with the data. The left and
right arrows move a cursor on the screen following the
datas. This is simple to do with a stl vector. How can
I browse the data counter back in a ListStore?

For now, I duplicate(!) the datas : the same datas are
in a ListeStore and in a stl vector (this is
inefficient, that's why I ask you for a solution...),
and I use the one or the other if I have to do
something or something else. Problem arises when i
want to delete some datas and keep the two
synchronised. Does anyone know how to solve this and
avoid this stupid duplication of datas?

Thank you in advance for your answers.
Eric
